CORRECTIVE ACTION
Error Code 214 - Tophandler Forklift Sensor
Indication Failure
1. Inspect forklift proximity
switches for grease and dirt.
Clean proximity switch tips and
indicator lights as required.
2. Check
forklift
proximity
switches for secure mounting
and proper adjustment.
Tighten and adjust proximity
switches as required (WP 0074
00).
3. Remove tophandler junction
box cover and ensure that
circuit breakers F41, F42, and
F43 are not tripped. Check
wire from circuit breaker F42
to
connector
X181
for
damage.
a. Reset circuit breakers as
required (WP 0076 00).
b. Replace damaged connectors
(WP 0111 00).
4. Remove junction box X183
cover (located on left end of
tophandler)
and
check
voltage between junction box
X183 pin 3 and pin 4. Voltage
should be 20-25V.
a. If
voltage
is
present,
perform functional check
of
forklift
proximity
switches by placing a metal
object within 5 mm of tip of
each switch. Proximity
switch
indicator
lights
should illuminate.
If indicator lights did not
illuminate, replace proximity
switch (WP 0074 00).
b. If
indicator
lights
illuminate, check voltage at
junction box X183 pin 5
(for unlocked) and pin 6
(for locked).
If voltage is not present, replace
proximity switch (WP 0074 00).
5. Remove cover from junction
box X182 (located on top of
tophandler). Check voltage
between junction box X182
pin 4 and pin 5. Voltage
should be 20-25V.
If voltage is not as specified,
repair or replace cable from
junction box X183 to junction
box X182 (WP 0111 00).
